Glass balls are not only for the playing and decorating, but they have also big sense in the industry. They are used in the production of paints, lacquers, where they are used as the milling medium or the filler. Technical balls are used also in chemical and pharmaceutical industry. They can fill spaces, isolate, jet the surface, be used as the gasket. We can meet them in rol-onech, ink cartridges, in valves. Their usage depends only on the type of glass, which is used, size and the roundedness. The special position between technical balls have  precision glass balls. Such balls can be used for example as a part of optical machines. Balls are used also in rehabilitation, because they have big acupressure effects.
